Summary: This is my first real "brand name" case. I was a little skeptical when I bought the case and I was a little unsure whether it would be worth the amount of money I spent on it. The case came with 3 to 4 fans and the airflow through the case is exceptional, putting any other case I've had to shame. I would definitely recommend purchasing this case. It's sleek and simple and you absolutely get your money's worth.
Summary: I used this case for my first build and it made everything easier. The tool-less bays were easy to work with and the spacers for my motherboard (full ATX) were already attached and in the right spots out of the box. The fans that came with it seem to do an adequate job pushing air through and both worked like a charm, not the quietest, but not super loud (I don't notice them while playing games or streaming media).
Summary: Great Value, functional and lightweight. I have used this case in many builds. It is a great case for the gamer who wants good ventilation in a mature looking case. It blends with the decor of an office or home with ease. The USB 3.0 ports up front adds a nice touch. Plenty of fan mounting locations and easy motherboard mounting makes for an easy build.
Summary: This is by far the easiest case I've ever worked with and is really quick to build in. At this price point it's very hard to pick another case. The stock fans are fairly quiet and give decent air flow. If I had to find a fault it would be that the hard drive mounts are a little rattly.
Summary: If you are thinking about a new case, the Corsair 300R is perfect for any build. I read reviews pertaining to thin metal and cable routing nightmares but I cannot agree with them. The chassis is solid. There are plenty of cable slots to route wiring, I/O cables and my hand doesn't get cut or scraped making connections in the box. Theres plenty of room inside to customize with lighting, fans, coolers.
Summary: Excellent case with plenty of room... I wanted a case that didn't have too many frills and what not, but still have some style. This fit t he description perfectly - and if you wanted to, you can order a non-clear side panel for $10-$20 off the Corsair website. Unfortunately, it does not come with the grommets for cable management, so I ended up ordering those from their site (the 350D ones will work for this case).
Summary: Picked up one for $79.99. Highly recommended case. Even comes with small black cable ties and a bunch of different screws you can use on MB, HD, DVD drives and stuff. Side acrylic window panel is amazing. 2 pre-drilled holes for extra fans down the road. Bottom intake filter included (PSU area). 3/4" of the areas on top are open. 2 fans pre-installed (1 in the front and 1 on the back of case). Love the 2x 3.0USB on the front side. Very convenient.
Pros: Plenty of room, Tool-less HD Bays, Massive internal space to work with
Summary: So far no complaints. It looks clean and WAY BETTER IN PERSON! It does look like a nice 100 case with all the fan mounts and space it has inside. It fit my 12 inch R9 290. It has great airflow and easy to work with.Only problem I had was placing the mobo but I have huge hands. Could have more space in the back to hide cables but I made it work out. I would recommend this to anybody.
